Fatigue estimation using voice analysis

In the present article, we present a means to remotely and transparently estimate an individual's level of fatigue by quantifying changes in his or her voice characteristics. Using Voice analysis to estimate fatigue is unique from established cognitive measures in a number of ways: (1) speaking is a natural activity requiring no initial training or learning curve, (2) voice recording is a unobtrusive operation allowing the speakers to go about their normal work activities, (3) using telecommunication infrastructure (radio, telephone, etc.) a diffuse set of remote populations can be monitored at a central location, and (4) often, previously recorded voice data are available for post hoc analysis. By quantifying changes in the mathematical coefficients that describe the human speech production process, we were able to demonstrate that for speech sounds requiring a large average air flow, a speaker's voice changes in synchrony with both direct measures of fatigue and with changes predicted by the length of time awake.     

Repetition proportion biases masked priming of lexical decisions

Although subjects have little or no awareness of masked primes, Bodner and Masson (2001) found that priming of lexical decisions is often enhanced when masked repetition primes occur on a high proportion of trials. We used baseline prime conditions to specify the locus of this repetition proportion (RP) effect. In Experiments 1A and 1B, a .8-RP group showed more priming than did a .2-RP group, and this RP effect was due to both (1) increased facilitation from repetition primes and (2) increased interference from unrelated primes. In Experiment 2, we used the baseline condition to show that subjects are sensitive to RP rather than to the proportion of unrelated primes. Direct comparisons of a given prime condition (repetition, unrelated) across RP conditions were more stable than were comparisons relative to the baseline condition. The increased costs and benefits of repetition priming when RP is higher implicate a context-sensitive mechanism that constrains accounts of masked priming.     

Analysts who commit sexual boundary violations: a lost cause?

The causes of sexual misconduct by analysts are discussed, as is the viability of rehabilitation for different types of transgressors. Common misunderstandings about the transgressor (such as the assumption of psychopathy and the likelihood of multiple offenses) are countered with a summary of data derived from the evaluation and/or treatment of over two hundred cases, most of them one-time transgressors. The typical characteristics of the analyst or therapist who engages in sexual misconduct are presented and discussed as qualities that are to some extent present in analysts generally. The temptation to deny this universal vulnerability is viewed as effectively replicating the kind of vertical splitting or compartmentalization that makes one vulnerable to sexual misconduct in the first place.     

Developments in cognitive neuroscience: II. Implications for theories of transference

An integration of psychoanalytic theory with contemporary developments in cognitive neuroscience offers a useful perspective on long-standing controversies about the nature of transference, and a better understanding of the precise mechanisms by which transferential processes occur. Contemporary psychoanalytic views of transference are reviewed, and the many processes that constitute transference are described. Two issues that have emerged in different guises for several decades-the role of the analyst in eliciting transference, and the nature of "real" and "transferential" components of the therapeutic relationship-are reconsidered in the light of concepts such as connectionist networks. Although a useful analytic stance is one that allows the patient's enduring dynamics to dominate the analytic field, it is suggested, anonymity is neither a cognitive possibility nor the driving force behind most transference reactions, and the distinction between "real" and "transferential" perceptions is one of therapeutic interest, not of mechanism. Certain features of the analytic situation make some dynamics more likely than others to enter the treatment relationship, notably those related to authority, intimacy and attachment, and sexuality. Transference reactions are best understood as constructed from a combination of the patient's enduring dispositions to react in particular ways under particular conditions; features of the analytic situation and of the analyst; and interactions between patient and analyst. These reactions do not unfold ineluctably from the patient's mind in the consulting room, nor are they cognitive constructions of the patient-analyst dyad or co-constructions of relatively equal partners exerting their influence on the analytic field.     

Observed classroom behavior of children with ADHD: relationship to gender and comorbidity

Examined hypothesized gender and comorbidity differences in the observed classroom behavior of children with attention deficit hyperactivity disorder (ADHD). The behavior of 403 boys and 99 girls with ADHD, ages 7–10, was compared (a) to observed, sex-specific classroom behavior norms, (b) by sex, and (c) by comorbid subgroups. Boys and girls with ADHD deviated significantly from classroom norms on 15/16 and 13/16 categories, respectively. Compared to comparison girls, girls with ADHD had relatively high rates of verbal aggression to children. Boys with ADHD engaged in more rule-breaking and externalizing behaviors than did girls with ADHD, but the sexes did not differ on more neutral, unobtrusive behaviors. The sex differences are consistent with notions of why girls with ADHD are identified and referred later than boys. Contrary to hypothesis, the presence of comorbid anxiety disorder (ANX) was not associated with behavioral suppression; yet, as hypothesized, children with a comorbid disruptive behavior disorder (DBD) had higher rates of rule-breaking, and impulsive and aggressive behavior, than did children with ADHD alone and those with ADHD+ANX. Elevated rates of ADHD behaviors were also observed in children with comorbid DBD, indicating that these behaviors are truly present and suggesting that reports of higher ADHD ratings in this subgroup are not simply a consequence of negative halo effects and rater biases.     

Cognitive and neuropsychological outcomes: more than IQ scores

Improved survival in preterm infants has broadened interest in cognitive and neuropsychological outcomes. The incidence of major disabilities (moderate/severe mental retardation, neurosensory disorders, epilepsy, cerebral palsy) has remained consistent, but high prevalence/low severity dysfunctions (learning disabilities, ADHD, borderline mental retardation, specific neuropsychological deficits, behavioral disorders) have increased. The follow-up literature contains methodologic problems that make generalizations regarding outcome difficult, and these are discussed. Although mean IQs of former VLBW infants generally are in the low average range and are 3-9 points below normal birth weight peers, these scores mask subtle deficits in: visual-motor and visual-perceptual abilities, complex language functions, academics (reading, mathematics, spelling and writing), and attentional skills. There is an increased incidence of non-verbal learning disabilities, need for special educational assistance, and behavioral disorders in children born prematurely. Males have more problems, and there is a trend for worsening outcome over time, due to emergence of more subtle deficits in response to increased performance demands. In addition to IQ and achievement testing in follow-up, there should be evaluation of executive functions and attention, language, sensorimotor functions, visuospatial processes, memory and learning, and behavioral adjustment.     

Effects of aging on action-intentional programming

Background: Action-intentional programs control “when” we initiate, inhibit, continue, and stop motor actions. The purpose of this study was to learn if there are changes in the action-intentional system with healthy aging, and if these changes are asymmetrical (right versus left upper limb) or related to impaired interhemispheric communication. Methods: We administered tests of action-intention to 41 middle-aged and older adults (61.9 ± 12.3 years). Results: Regression analyses revealed that older age predicted a decrement in performance for tests of crossed motor response inhibition as well as slower motor initiation with the left hand. Conclusion: Changes in action-intention with aging appear to be related to alterations of interhemispheric communication and/or age-related right hemisphere dysfunction; however, further research is needed to identify the mechanisms for age-related changes in the brain networks that mediate action-intention.     

Presidential Scandal and Leadership: A Natural Laboratory Test of the Resiliency of President Clinton's Transformational Leadership During the Impeachment Crisis1

This study examined transformational and charismatic leadership assessments of President Clinton over 4 time periods beginning with his second term, continuing through the scandal of the Monica Lewinsky case and impeachment trial, and ending after he was acquitted. Our findings indicate that as the scandal unfolded, in general his leadership ratings declined among Democrats, Republicans, and “Others” (including Independents). However, his ratings did not decline at the same rate among all groups. They appeared to decline much more steeply with Republicans than with the other 2 groups. We discuss the differences in rates of decline among different factors of transformational leadership and the implications of the study for future research.     

Narcissism, Perfectionism, and Self-Termination from Treatment in Outpatient Cocaine Users

This study examines perfectionism in individuals with a Diagnostic and Statistical Manual-IV, Text Revised [American Psychiatric Association, 2000. Diagnostic and statistical manual of mental disorders (4th ed.). Text revision (DSM-TV-TR). Washington, DC: American Psychiatric Association] diagnosis of Narcissistic Personality Disorder and a coexisting diagnosis of cocaine abuse or dependence. Participating clients were treated in outpatient settings that provided cognitive-behavioral therapy. Clients were administered Hewitt and Flett's (1991b) [Journal of Personality and Social Psychology, 60, 456-470] Multidimensional Perfectionism Scale prior to treatment. Scores for dimensions of perfectionism were compared with those obtained from cocaine abusers in treatment with diagnoses of Antisocial Personality or Affective Disorder. Clients with Narcissistic Personality Disorder were characterized by relatively higher levels of other-oriented and socially prescribed perfectionism. Survival analysis suggests that self-termination from treatment by cocaine-abusing clients with a diagnosis of Narcissistic Disorder is related to high levels of other-oriented perfectionism. The clinical implications and limits of this study are discussed.
